The number of installations of photovoltaic installations for renewable energy generation is increasing significantly worldwide. Not surprisingly, this is a technology with huge potential, with the sun as the main source whose power needs to be harnessed.

The main limitation at the moment is that, in general, the time of day when the most electricity is generated by PV panels does not coincide with the time when demand is highest, as shown in the graph.

This generally means that during the morning, afternoon and evening there is not enough PV generation to meet the demand for electricity, and on the other hand, more electricity is generated during midday than the investor needs at that time, thus creating a surplus.

In order to make the best use of the PV system, it is essential to store the resulting surplus so that it is available at the time of greatest need.

Currently, surpluses are stored through accumulators.

However, such a solution has a number of disadvantages:

• high costs
• limited power
• limited service life
• contaminants

ecoGEO+ and ecoAIR+: the path to zero energy buildings

 

We have developed a technology that allows us to combine both renewable energy sources, i.e. heat pumps and photovoltaic devices, in a unique and much larger capacity.

Most importantly, we provide our customers with this solution at no additional cost, it is a standard part of all ecoGEO+ and ecoAIR+ heat pumps.

The key is to convert the surplus from photovoltaic installations into thermal energy, which is much easier and cheaper to store because it only requires a volume of water. That is, something we already have in our homes (in DHW tanks, underfloor heating, storage tanks, swimming pools, etc.).

When a surplus is generated from photovoltaics, the pumps increase their output (thanks to the inverter technology of all our heat pumps, i.e. the ability of the compressors to modulate their output), absorbing the surplus and converting it into thermal energy suitable for both cooling and heating.

In this way, we get much closer to a balance between the energy generated and the energy needed in our homes.

Automatic change of set values of all thermal requirements of the installation in the event of excess energy generated by photovoltaics, i.e. switching from basic temperature values to previously configured excess temperature values.

One of the key features of our heat pump technology is that, thanks to all our years of experience in managing and developing software and control strategies for variable capacity compressors (inverter technology), in our case, no electricity from the grid is ever consumed in a PV surplus situation.

The compressor output increases and adapts to this excess without exceeding it. If the available surplus electricity is not enough to reach 60°C in DHW, for example, it stays at 50°C, 55°C, etc., but always guarantees that no electricity is drawn from the grid, and this is a big difference compared to similar systems.

Although net zero balance is one of the most significant features of the hybridisation of heat pumps with photovoltaic systems, there are other very important features that confirm that the eco GEO and eco AIR series are unique:

 

SET YOUR LIMIT

It is possible to set a limit on the electricity consumed. If the total energy consumption of the house approaches this limit, the heat pump will reduce the energy consumption (inverter technology) to avoid exceeding it.

This is very important because it allows us to negotiate a lower contracted tariff for electricity consumption and therefore significant long-term savings on our electricity bills.

 

KEEP YOUR TARIFF UNDER CONTROL

Our heat pumps allow individual electricity tariff settings for peak and off-peak periods in summer and winter. The pumps produce more energy when electricity is cheaper and reduce consumption when it is more expensive. This allows further significant savings on electricity bills.

The E-system is designed to enable the connection between the heat pump and the PV system in the most advanced and efficient way, but also in the most compact way.

In combination with the heat pump, the E-system is an added technology with all the advantages and features described above, but also with a photovoltaic inverter and even with 1 to 5 storage batteries that can act as a supplement to store the heat generated by the heat pump.

For situations where electricity production drops, the energy stored in the batteries is still able to cover the household's electricity consumption. In addition, its modularity allows the storage capacity to be expanded at any time with a very simple installation.

If you want your installation to be unique, efficient and economical, get ahead of the future by combining a heat pump with photovoltaic panels from us and take ownership of your own energy. Whether you are interested in installations with thermal requirements of just a few kW to those requiring several hundred kW.
